MINE-PUMP.

Specification of Letters Patent. Patented NOV. 11, 191 3.

Application filed December 4, 1912. Serial No. 734,932.

To all whom it may concern:

Be it known that I, LEWIS GHADWIoK, a citizen of the United States of America, residing at Nelsonville, in the county of Athens andState of Ohio, have invented certain new and useful Improvements in Mine-Pumps, of which the following is a specification.

This invention relates to mine pumps, and contemplates the provision of an improved structure of this character more fully set forth in the following detailed description, and illustrated in the accompanying drawings, in which Figure 1 is a front elevation of a mine pump, constructed in accordance wlth the invention. Fig. 2'is a transverse sectional view therethrough. Fig. 3 is a longitudinal sectional view therethrough, and Fig. 4: is a transverse section through the pump cylinder. a

Like numerals designate corresponding parts in all of the figures of the drawing.

It is a well known fact that mine pumps constructed of metal, deteriorate rapidly, by reason of the presence of acids within the water pumped from mines, and it has been heretofore proposed to construct mine pumps of wood to thereby more effectually resist the action of such acids.

The present invention contemplates the provision of an improved pump of this type in which the various parts are made of acid resistant material and in which the pump comprises a plurality of blocks of wood suitably secured together, and having the necessary ports and chambers formed therein.

It is a further object of the invention to provide a pump of this character having a cylinder lined with glass or like acid resisting material and having glass ball valves and having separate and detachable valve seats arranged in such manner as to be readily and conveniently clamped in place by the placing together of the sections of the ump.

Further objects and advantages of the invention will be set forth in the detailed description which now follows.

The pump forming the subject matter of the present invention comprises a supply deck 5, a cylinder deck 6 and a discharge deck 7 The supply deck 5 is located at thebottom and has a supply conduit 8 formed longitudinally therein, said conduit connecting with vertical channels 9, formed partially in the supply deck 5 andpartiallyan Y the cylinder deck 6. Clamped to the rear of cylinder deck" 6 is a block 6 containing the cylinder. The cylinder is formed by boring the block 6. longitudinally at 10.to communicate with longitudinal channels 11 and '11 formed partially the cylinder deck and partially in the block 6. The cylinders 10 are preferably lined with glass, porcelain orlike acid resistant material indicated at 12. A plunger 13 is disposed in the cylinder and may be operated through the medium of rod 14, which passes through stuffing box 15. This stuffing box comprises a gland 16 which acts to force the packing material against'a washer 17 which has a seating against a shoulder 18. The block 6 is bored out at 19 to permit of the insertion of the lining 12.

The intake valve comprises a wooden valve seat 20 in which a glass ball valve 21 has a seating. Ribs 22 limit the upward movementof said valve without interfering with the passage of the water. The valve is provided with a horizontal flange 23 which is clamped between the sections 5 and 6 when the sections are assembled, whereby said valve is effectually held in place, but is readily detachable if for any reason it is desired to remove it. In like manner the discharge valve comprises valve block 2 1 having a valve seat formed therein upon which a glass ball valve 25 seats, and said block is provided with a horizontal flange 26 adapted to be held between the sections 6 and 7 when the pump is assembled. The discharge valve discharges into passage 27 and into a discharge conduit28 and from said discharge conduit through discharge conduits 29 and 30 formed partly in the section 6 and partly in thesection 7. Secured to the out-er end walls ofsection 6 arestraps 31, and these straps at their lower ends, are threaded for thereceptionofnuts 32 which clamp longitudinal bars 33 against the underside of section 5. Hingedly con nected to the upper ends of straps 31 are rods 34, the upper ends of which are threaded for the reception of nuts 35, these nuts in turn acting to force bars 36 against the top section 7, so that it will be apparent that the top and bottom sections are thereby firmly bound to the central section ,6. Strap 36 extends around the cylinder block 6'. Bolts 37 pass through strap 36 and into section 6 and thus tend to press block 6 against the packing 38 to prevent leakage between the two parts 6 and 8. Strap 39 passes over the top of block 6 and around a suitable support shown atieO. A cap 41 is held in place by; screws 42 ,and serves to close the bore 19.

It willrb'e seen that whenthe-plun'ger 13 j is moved in one direction, a suction will be created in the cylinder, and channels 11 and 1 allowing thelfiuid to flow and allowthe water to flow through port Y 7 28, part of it and part in'port V r I is taking place,

V i plunger action is accomplished in the'other channel,

andthereby gives a double-acting service.

' It is believed that theoperation of this degoingv into discharge port 30, 29. While this discharging the suction in channel 11 caused by the forward movement of the plunger is drawingjwater in, and when the i is again moved backward, the same vice'will be apparent from the structure set forth.' The pump comprisesa cylinder with two outlet channels, said cylinder being double-acting.

it While the elements shown and described are well adapted to serve the purposes for the intake valve will close ed claim.

Having described my invention, what I cla1m 1s A wooden mine pump formed of three superimposed blocks, the lowermost of said blocks being. channeled to form an :intake passage, the intermediate one of said blocks having a pair of separated vertical channels formed therethrough, intake valves comprising valve blocks having horizontal flanges which are clamped between the lower and the intermediate sections and across said vertical channels, discharge valves comprising separate blocks having transverse flanges I clamped between the intermediate and the uppermost section and across said vertical channels and the uppermost of said blocks being channeled to form a discharge passage.

In testimony whereof I aflix my signature in presence of two witnesses.
